TROLLEY-SLEETER.

SPECIFICATION forming part of Letters Patent NO. 618,577, dated January 31, 1899. Application tiled JannaryZS, 1898. Serial No. 668,272. (No model.)

To all whom it may con/cern:

Be it known that I, JAMES B. MocK, a citizen of the United States, residing at Fort IVayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in 'Irolley-Sleeters; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to the figures of reference marked thereon, I

which form a part of this specification.

My invention relates to improvements in trolley-sleeters of the class in which the device is attached to the trolley-pole of an electric car and is adapted to cut ice and sleet otf the conductor-Wire as it is moved against it by the pole; and the objects of my improvement are, first, to provide a device which may remain attached to the pole; second, to afford facilities for its adjustment, and, third, to provide an improved device of the class named Which shall be more economical, efficient, and more easily adjusted.

Other objects and advantages Willhereinafter appear; and the invention consists in the construction and novel combination and arrangement of the parts hereinafter described, pointed out in the appended claims, and illustrated in the accompanying drawings, in Which- Figure lis a side View of the device. Fig. 2 is a top view, and Fig. 3 is a View of the icecleaner and its arm.

Similar numerals of reference refer to similar parts throughout the several views.

The ice-cleaner 4 consists of a curved metal bar adapted to conform to the curve of the trolley 5, so that it Will lie in close contact and within the groove 6 of the Wheel. It is attached, preferably, integrally to an arm 7, having at its end means to engage a spring 8 to hold it in place-in the present instance a squared end with opposite faces slightly inclined-'the spring 8 acting thereon like the spring in a knife which holds the blade in position. The ice-cleaner 4 may have its upper face 9, which impinges against the conductor-Wire, provided with teeth, as shown in Fig. 3, or it may be smooth. This upper face 9 is grooved or .hollowed out to partly embrace the wire, and the edges thereof are preferably made acute, so as to form cutting edges.

The preferable method of attachment to the trolley-pole lO is to construct a frame 11, having three points of attachment to the pole, the center one, 12., being secured by bolts and clip 13. The ice-cleaner 4 and its arm 7 lie Within the frame, as shown by the drawings, the arm being pivoted to the top end of the frame, Where its square end rests upon the spring-plate 8.

The mode of operation is as follows: The device being secured to the trolley-pole, as shown in Fig. 1, the ice-cleaner 4 is drawn back with the frame, as shown by the dotted lines, and it is held iirmly in this position by the spring 'S acting as described. When it is desired to use the ice-cleaner, it is raised and thrown forward into the trolley-wheel 5, as shown by the dotted lines in Fig. 1, and is held there by the spring 8. The pole is then adjusted to the conductor-wire, and the icecleaner 4 cuts and removes the ice and sleet therefrom by its passage, at the same time protecting the trolley-Wheel and forming a conductor for the electricity to pass from the Wheel to the wire without resistance. The entire device, being so constructed, has but little weight to impede the action of the trolley-pole springs in holding the wheel and cleaner against the conductor -wire. The frame 11 can be made very light, as its only functions are to permit a pivoted attachment of the arm 7 and the holding of the spring to alternately hold the ice-cleaner in or out of position, as desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is*

1. In a trolley-sleeter of the class named an ice-clearer consisting of a metallic bar formed and curved to lie within part of the groove of a trolley-Wheel, and provided With a groove for the wire, the groove forming cutting edges to cut the ice; a frame for holding the iceclearer firmly attached to the trolley-pole; an arm for the clearer pivoted to the frame, the arm provided at its pivoted end with extensions adapted to form bearings for a spring;

and a spring operating against the said bearings alternately to hold the arm in and out of position. f

2. In a troll'ey-sleeter of the Glass named, an ice-clearer consisting of a metallic bar formed and curved to lie Within part of the groove of the trolley-Wheel and provided with a groove for the wire, the groove forming Cutting edges to out the ice; an arm for holding the same in place secured pivotally to the trolley-pole, and means to hold the arm in and out of position Without cha-n ging its connection to the pole.

3. In a trolley-sleeter of he Class named, :L

frame for holding an ice-clearer; an ice-clearer provided with an arm pivoted to the frame, the arm provided at its pivoted end with extensions adapted to forni bearings for a springt; a spring operating against said bearings a1- ternately to hold the arm in and ont of position; and means to attach the frame firmly to the trolley-pole.

In testimony whereof I affix my signature in presence of two Witnesses.
